Be it known that I, Geenen H. CHAPEL, va

. citizen of the United States, residing at Howell, in the county of Livingston and State of v Michigan, have invented certain new and useful Improvements in Eyeglasses, of which the` following a specification. K i g' This invention relates in general to noseglasses, and more particularly to the construction and arrangement of the various parts or devices thereof eeperating collectively for retaining the same topplace uponthe nose of :the wearer and individually for supporting thel lenses.y in: proper lposition with respect to the eyesand ,hasv special. reference vto im- 'provementsupon the patent issued-'to me The object of the invention is tol provide a connection between the'lens, brackets, and nose-bridge pivoted to the lenses'4 by oneand the same means. .A I Y With thesev and ValjQlls.otherfobjeeta advantages,and improved results in view the invention ,consistsy in vthe novel .construction and arrangement of 'parts wherein a=rigid.con'.

nection is made between the Vlensfanel the guards and .between the bridge` and the lens as regards vertical movement'ef the latterv and with respect to any spring action on .the part spectiveyiew. Fig'. 2 is a top viewshewing in dottedA lines the movement of the lens.

the drawings.

In the glasses coming under the classes here- -The same numeral references denote th same parts throughout the several views of .aren inbefore referred to and those of various other characters the lcnsclamp or bracket is necessarily extended from the lcns'fedge and madev with a socket or in similar form to afford a base, post, or other elementto which the -bridge and guards aresecured. In the apthe opening 6 in the lens-bracket.V The earsA have central apertures 7, the lower one of'A which is screw-threaded. This arrangement of the earsobviates making the usualneck, lug, or projection from the bracket for connecting other parts of the device, and it af fords a closer union of the parts'of my inventien with the lens. i

The nose-guards 8 have preferably a curled top wing 9 with corrugated surface forming an aperture 10, a bottom wing 11, and 'a stem l2 allV struck up froma iiat piece, end 13 brought to right angles to the said wings by prevents its moving when clamped toplace by a shoulder 14 -on a screw-stud 23. The nose-bridge 16 is not of spring metal,l and it is therefore not resilient in' the least, but is capable of being bent, if necessary, to suit various forms or shapes of the nose, though ordinarily such bending will not be found necessary, inasmuch as the bridge is only, in? tended as a connection between tlielenses and notte rest on or otherwise engage the nose. The bridge 16 has circular-shaped fiat ends 17, which are turned outwardly and forwardly from the bridge to leave a neck 17 The ends 17 have an aperture 18 and edge stop-lugs .19, which engage the base edge of the slot 5 to limit the movement of the lenses, which with theguards are Vcontrolled by a bowed or U' Vshaped spring 20, having coils and hook ends 22',"and the bridge and guards are connected together and to the lenses bya screw-stud 23,

having a journal-bearing 24: for the bridge ends 17. ln assembling the parts both lens connec- IOO tions being the same only one will be referred to. 'Ihe bracket 2 having been clamped to a lens, the fiat end of the guard and of the nosebrid'ge is-placed in the slot 5 with the bottom ofthe U-shaped spring resting in the neck ofthe bridge and the ends of the spring hooked over the front edge of the lens-bearing 3. Then. thestud is inserted through the spring-coils and through the top ear, bridge end, and guard end 4into the screw-aperture of the bottom ear..

, Referring to the modification shown in Fig. 8, the nose'- guard 25 is made in the same piece with the bottom ear 26 of the lensbracket 27. Otherwise this construction isv the same as the preferred form.

It is well known. that. next to preparing .lenses for correct vision it is of greatest importance to keep the lens against vertical movement, vso that the vision may be through the center of the. lens, for the least vertical variation will deect the vision and impair the sight. Hence the importance of fixing the lenses permanently against vertical movement in placing and removing the glasses. This is fully'accomplished by the inflexible bridge vhaving such connection with the lens and guards as to permit opening .and closing of the latter in the plane of vision without the least vertical movement of the lenses or any ofthe parts of the device. 4

Having thus described my-inventio'n, what I claim as new, and desire to secure by Letters Patent, is-rv l. Ineyeglasses having the guards fixed to the lenses and adapted to be moved bythe movement of the latter in the plane of vision, a nose-bridge connecting the lenses rigidly against vertical movement, a studl to fix the guards and pivot the bridge so as to permit horizontal movement 'of the lenses on the bridge, and a spring held by the stud ends and extending centrally from the studs onto the' bridge to efecta pressure on the nose by the guards.

2. In eyeglasses, the one-piece 'lens-brackets having a slot at right. angles to the lenses, guards provided with securing ends having a straight edge to engage the base of the slot, a bridge, and a stud at each end of the bridge to pivot the latter and to tix the guards.

3.k In eyeglasses, a nose-bridge having ends provided with stop-lugs, lens-brackets having a slot the base edges of which engage the 'said lugs to limit the movement ot' thc lens,

, 5. -In eyeglasses, the lens-brackets, guards having stud-apertures, thel nose-bridge havlng stud-apertures, screw-studs extendlng through said apertures to fix the guards and vpivot the bridge to the brackets, and the springs held by the studs and having a portion engaging the bridge with the spring ends engaging the brackets.

6. In eyeglasses, the combination, with the lens-brackets, having a slot at right angles to the lenses, and nose-guardsA fitting the slot and having ends provided with a straight edge to engage the base of the slot, of the nose-bridge having ends fitting the slot and provided with stop-lugs adapted to be engaged by the base edges of the slot to limit the pivot movement of the lenses and guards, springs looped over the bridge with their ends engaging the brackets to give the `guards pressure on the nose, and the studs fixing the guards tothe brackets and forming a pivot for the lenses. A

7. 1n stii-bridge eyeglasses, having lenses movable in line with the plane of vislon, the

combination, with the lens-brackets having' ears with a slot therebetween at right angles to the lenses, and guards or plaquettes fitting thc slots, of the bridge having necks and ends which fit the said slots, springs having' a bow fitting the bridge-necks with coils resting on the said ears and the ends of the springs engaging the lens-brackets, and the studs extending through the coils and ears to fix the guards to the lenses and to pivot the latter 'against vertical movement.

In witness whereof I hereunto set my hand in the presence of two witnesses.
